Description

Method and device for establishing data radio bearer

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for establishing a data radio bearer.

Background technique

With the development of communication technology, the total number of devices connected to the global mobile communication network will reach 100 billion. It is estimated that by 2020, the number of global mobile terminals (excluding IoT devices) will exceed 10 billion, of which China will exceed 2 billion. As the number of terminals increases, reducing the transmission delay during data transmission becomes an urgent problem to be solved. .

Currently, when the terminal is in the idle state, if data is to be sent or received, the relevant bearer is first established, and then the relevant bearer is used to send or receive data. The specific process is as follows:

Step a: Establish an RRC (Radio Resource Control) connection in an idle state, and enter an RRC connection state, that is, establish a signaling bearer;

Step b: transmitting the RRC message by using the established signaling bearer to establish a data bearer;

Step c: Data transmission or reception is performed using the established data bearer.

Wherein, during the connected state, if the terminal moves, the cell handover is performed.

Further, after the step c, when the terminal does not send or receive data, the RRC connection release process may be performed, and then the terminal returns to the idle state.

Further, when the terminal needs to send or receive data again, the above process is repeated.

With the rapid increase in the number of terminals, the amount of data transmitted by the terminal is also increasing in an explosive manner. If the transmission is still performed in the above manner, there is a drawback that it takes a long time and is inefficient.
